FWIW when one of the gambling houses applied their model to the Weeks 1 through 16 games, they had the Dolphins going 8-7 heading into the Week 17 game against the 15-0 Patriots.
It was the same company responsible for these over/unders, Cantor Gaming. They are a new outfit that has stormed into Las Vegas the past few years, first establishing themselves at new casinos like M Resort and Cosmopolitan, and now spreading their greasy fingers to formerly independent or Leroy's sportsbooks like Venetian, Palms, Hard Rock, Tropicana.
Bright red and yellow lights on the betting boards, and loud screens in your face at every seat. I guess it's the Oregon uniform version of sports betting. Locals aren't impressed, primarily because Cantor doesn't offer anything unique or bold in terms of betting options, and they have a stuffy attitude at the counter.
Along with scared pathetic limits. $3000 on season win over/unders is a joke, considering they hold your money for half a year. Gene Mayday of Little Caesar's casino must be rolling in his grave in hysterics. Twenty years ago in his tiny strip mall casino, on the current lot of Paris, Mayday would put up over/unders with a stated limit of $100,000, but a note saying, "Ask if you need more." More meant anything you wanted to play. I used to watch celebrities and big shot gamblers walk into his back office with a briefcase. Bob Stupak made the famous million dollar bet on the '89 Super Bowl at Little Caesar's. Mayday called me aside and told me he had taken many wagers larger than that. Those bettors simply didn't seek the publicity, unlike eccentric Stupak, then owner of Stratosphere.
These days Cantor Gaming somehow earns loud headlines with a 3 dime limit. That's the way Las Vegas has trended...corporate cookie cutter mentality taking the place of aggressive former bookmakers.
Anyway, Cantor still has the weekly spreads with the Dolphins favored 7 or 8 times in individual games, and New England favored perhaps across the board. I haven't checked specifically. But as I described in the related thread here a month ago, you can't merely add up the number of times a team is favored and pronounce that is their over/under. The writer of the article on the Dolphin site made that mistake. Even if New England was favored in all 16 games by 7 points or more, does anyone actually believe the over/under is 16? You might get a little bit of under money. Like a non stop line at the window until you adjusted severely. Every level of favoritism carries related win likelihood. A 7 point favorite equates to a win expectancy of roughly -300 (3 in 4). That's why the best teams that are favored virtually every week still figure to lose 3-5 games, under typical distribution.
Granted, these days in an imbalanced league with moronic teams throwing it 40+ times with mush quarterbacks, it scares the heck out of me toward somebody matching '72 and unbeaten. Contrast used to defeat the powerhouses on any given you know what. Force the same style and somebody who simply does it better will trump you virtually every time.
In that month ago thread I estimated Miami's over/under would be 7 over or 7.5 under. This number seems a bit high, since the juice on the under 7.5 is only -120 (120 to win 100). I expected -130 or more. I certainly wouldn't be in a rush to bet the over and pay -110. (Nice 30 cent line, BTW, another wimpy practice that would make Mayday chuckle). The sharp bettors overwhelmingly look to bet under on these lines while the public forces the over. Any team with the threat of a rookie quarterback playing, and with the number 7 or higher, generally draws under money. I would expect the juice on under 7.5 to push to -130 or greater, and it's not inconceivable some joints could hang a 7 (juiced over) later on.
Cantor is hardly the ultimate authority. And "applied their model" is allowing far too much credit. I wish everyone could work in a sportsbook for a day or two. That's all it would take to rid the mythology of sophistication. Companies like that are life and death to make sure everybody shows up to work, and for the lines on the screen to match what is in the computer. These days sports power ratings are very good, and many widely available sources. That's the sportsbook edge. They basically average the power ratings and spit out an accurate appraisal, just like political polling experts like Mark Blumenthal average the reputable polls for a valid representation of the race.
